Simulations

Updated 1/10/2013: CLUBB provided a new coupled simulation starting from the large-ensemble. Older simulations (previous tp Dec 30,2014) can be found here.

ID	Case Description	Diagnostics	Details/Comments
f2000_clubb	CAM standalone with climatological SSTs	w/ obs w/ cam5.3 (5-year run)
f2000_pia_clubb	CAM standalone with climatological SSTs + preindustrial aerosol	w/ f2000_clubb
famip_clubb	AMIP run + COSP simulator	w/ obs (yrs 1980-2004) * w/ cam5.3 (yrs 1980-2004) w/ obs (yrs 1995-2004) * w/ cam5.3 + cosp ** AMWG variability CVPD package	(*) The COSP simulator for 1980-2004 have a bug (independant of CLUBB). We reran 10 years with the bugfix (1995-2004) (**) The cam5.3 didn't include COSP simulator. At the panel's request, we ran a 10-year simulation with COSP turned on.

Description of the code base and difference with CAM trunk

The clubb simulations used code branched from cam5_3_08.
The description of the code is available on the CLUBB tag description.

This document includes:

• list of the tuning parameters (different from CAM5 tuning) used in CLUBB simulations
• list of changes unrelated to CLUBB used in CLUBB simulations

Timings

CLUBB timings are available on the Timing table
